latter of nearly equal width throughout, not prominent and but gently sulcate at 

 the ocellus; occiput short and only gently elevated. Antenuaj slender, a little 

 shorter than head and pronotum combined, the basal joint smaller than usual, 

 orange colored. I'ronotum smooth, gradually widening behind, without well-<letined 

 carinas, the transverse grooves all very distinct and the border rather widely nuir- 

 gined throughout; hind margin broadly rounded. Tegmina small, lobate, their 

 extremities reaching to the middle of second abdominal segment, and with their 

 inner edges rather widely separated. Abdomen short, the sides but little com- 

 l)re8sed, the dorsal carina nearly obsolete, and the apex blunt, in the male gently 

 enlarged and ending in a blunt upwardly directed point, as in HehperotetHx viridia 

 Thos. Supra-aual i)late of male abdomen triangular, quite broadly and deei)ly 

 grooved on basal half and provided with a rather prominent carina on each side 

 that extends from the outer basal angles to the apex of the mesial sulcus; marginal 

 apophyses of preceding segment obliterated. Male cerci straight, rather wide and 

 compressed at base, tapering rapidly to middle, from which point they are slender 

 and finger like, directed slightly backward, inward, and upward. Valves of the 

 ovipositor short, slender, their apices strongly hooked, the basal tooth of lower 

 pair quite large and triangular. Posterior femora rather heavy, reaching the tij) of 

 abdomen in both sexes. Prosternal spine rather heavy, short, pyramidal, a little 

 transverse.

Habitat : This iusect was collected by me at Grand Junction, Colo., 

 wliere it was present in very large numbers during the month of June. 

 It seemed to be confined in its distribution chiefly to the grease-wood 

 clusters, and was known by the popular name of grease-wood hopjjer. 



According to the method employed and the characters used by Carl 

 Brunner von Wattenwyl in his recent work entitled " Eevision du 

 Systeme des Orthopteres/' this insect would naturally fall into the 

 genus Hesperotettis of Scudder; but, since it has been the custom of 

 American writers prior to this to place all short-winged acridians in the 

 genus Pezotettix, I shall follow this custom here. It is quite evident, 

 however, that this group will very shortly have to be revised for the 

 entire country. This should certainly be done, because it is a very 

 extensive one, there being fully 200 distinct species in North Aiiierica 

 alone, all more or less destructive in their food-habits. Many of them 

 are also confined, like the present species, to special food plants. 



A MARITIME SPECIES OF COCCID^. 



By T. D. A. CocKEKELL, Las Cruces, 2\\ Mex. 



Ripersia maritima Ckll., n. sp. 



Female about 1^"'™ long, plump, elongate-oval, naked, pure white, segmentation 

 distinct, legs and antennaj slightly brownish. 



When boiled in caustic soda the female turns bright yellow — a curious reaction. 



Antenna^, 6-joiuted; 6 longest, a little longer than 4 and 5; 3 and 1 about equal; 

 2, 4, and 5 subcqual and shortest. Formula G (13) (245). Each joint emits a few 

 hairs; the sixth several. The antenuie are very small and short, and placed 

 extremely close to one another, as in 7i. rumicis. 



Derm with numerous but scattered short linirs, and round gland-spots.
